Description

Technical Field

[0001] The utility model relates to the technical field of aluminum honeycomb panel detection, in particular to an auxiliary device for detecting the compressive strength of an aluminum honeycomb panel. Background Art

[0002] Aluminum honeycomb panels are suitable for civil construction, vehicle and vessel decoration, and other applications. They represent the application of aviation and aerospace materials in the civil construction field. The entire process is completed in a modern factory using hot-pressing technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb, the inner and outer skins expand and contract synchronously with each other. Small holes in the honeycomb aluminum skin allow for free flow of air within the panel, and a sliding mounting buckle system prevents structural deformation due to thermal expansion and contraction.

[0003] In practical applications, the compressive strength of aluminum honeycomb panels is one of the indicators for evaluating their quality. However, the commonly used compressive strength testing devices are not convenient to move to a predetermined position according to the needs of use, and they occupy a fixed space and have limitations in use.

[0006] The moving component includes a hydraulic cylinder 2, a base plate and a roller. The hydraulic cylinder 2 is installed on the side wall of the support. The base plate is installed at the output end of the hydraulic cylinder 2 and moves up and down along the guide rail fixed on the support. The roller is fixedly installed at the bottom of the base plate.

[0007] By adopting the above technical solution, the device can be easily moved and retracted to reduce its footprint when not in use. In addition, the support can be adjusted in real time according to the different sizes of aluminum honeycomb panels to facilitate the compressive strength testing of the aluminum honeycomb panels.

[0008] The detection assembly includes a telescopic arm, a hydraulic cylinder 1, a pressure sensor and a pressure-applying part. The telescopic arm is installed between the upper ends of two groups of supports. The hydraulic cylinder 1 is installed on the telescopic arm through a fixed plate. The pressure sensor is installed at the output end of the hydraulic cylinder 1, and the pressure-applying part is fixedly installed at the bottom of the pressure sensor.

[0009] By adopting the above technical solution, the compression resistance test of the aluminum honeycomb panel is carried out.

[0010] The telescopic arms are provided in two configurations, and the telescopic arms are multi-stage telescopic structures. The hydraulic cylinder 1 is installed at the middle of the telescopic arms through a fixing plate.

[0011] By adopting the above technical solution, the position of the hydraulic cylinder 1 can be adjusted to perform compression testing on the aluminum honeycomb panel.

[0012] The fixing ring is provided with a bulge, which is provided with a through hole. The limiting ring is provided with a plurality of through holes. The limiting pin passes through the through hole at the fixing ring bulge and extends through the through hole of the limiting ring.

[0014] The bottom surface of the guide rail is flush with the bottom support surface of the support.

[0015] By adopting the above technical solution, it is ensured that the bottom plate drives the roller to move vertically up and down.

[0016] The beneficial effects of the utility model's auxiliary device for detecting the compressive strength of aluminum honeycomb panels are:

[0017] The second hydraulic cylinder can be driven to push the bottom plate to move downward along the guide rail so that the roller contacts the ground until the support is supported. After that, the two sets of supports can be pushed and pulled according to the size of the aluminum honeycomb panel to adjust the distance between the two sets of supports. After the distance between the two sets of supports is adjusted, the limit pin can be inserted into the upper end of the fixing ring and the through hole on the limit ring to limit the threaded barrel from continuing to rotate. At this time, the lead screw is restricted and no longer moves, which makes it easy to move the device and can be retracted. When not in use, its footprint is reduced, and the support can be adjusted in real time according to the aluminum honeycomb panels of different sizes to facilitate the compressive strength test of the aluminum honeycomb panels.

[0024] The moving assembly includes a hydraulic cylinder 2 11, a base plate 13 and a roller 14. The hydraulic cylinder 2 11 is installed on the side wall of the support 1. The base plate 13 is installed at the output end of the hydraulic cylinder 2 11 and moves up and down along the guide rail 12 fixed on the support 1. The roller 14 is fixedly installed at the bottom of the base plate 13.

[0025] The hydraulic cylinder 11 can be driven to push the bottom plate 13 downward along the guide rail 12, so that the roller 14 contacts the ground until the support 1 is supported. After that, the two sets of supports 1 can be pushed and pulled according to the size of the aluminum honeycomb panel to adjust the distance between the two sets of supports 1. (In the process of pushing and pulling the support 1, the length of the screw 6 extending into the sleeve 7 will change. At this time, when the screw 6 moves, the threaded barrel 15 will be forced to rotate to ensure that the screw 6 moves normally. After the distance between the two sets of supports 1 is adjusted, the limit pin 10 can be inserted into the through hole on the upper end of the fixing ring 8 and the limit ring 9, thereby limiting the threaded barrel 15 from continuing to rotate. At this time, the screw 6 is restricted and no longer moves.)

[0026] The aluminum honeycomb plate is placed between the two groups of supports 1, and then the hydraulic cylinder one 3 is driven to push the pressure sensor 4 and the pressing part 5 to move downwards, the pressing part 5 presses the aluminum honeycomb plate, and the pressure data transmitted back by the pressure sensor 4 are detected in real time.

[0028] The fixing ring 8 is provided with a protrusion, the protrusion is provided with a through hole, a plurality of through holes are formed around the limiting ring 9, and the limiting pin 10 extends through the through hole of the protrusion of the fixing ring 8 and the through hole of the limiting ring 9; since the threaded cylinder 15 and the lead screw 6 are in threaded connection, in order to ensure that the distance between the two groups of supports 1 can be adjusted, when the two groups of supports 1 are close to each other, the lead screw 6 continues to move into the sleeve 7, at this time, the threaded cylinder 15 rotates on the fixing ring 8, after the position adjustment is completed, the limiting pin 10 can be inserted into the fixing ring 8 and the limiting ring 9, and the rotation of the limiting ring 9 is limited; since the limiting ring 9 is fixed to the outer wall of the threaded cylinder 15, at this time, the threaded cylinder 15 is also limited to rotate, and at this time, the lead screw 6 is limited to move transversely.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a plurality of modifications and improvements can be made, and these all belong to the protection range of the utility model.
